JBL SRX918S 18" Powered Subwoofer

The JBL SRX918S 18" powered subwoofer is designed to deliver massive low end for live sound reinforcement and recording applications. With dual 18" woofers, 3,000W of power and intelligent processing, it produces tight, defined bass that you can feel. Its rugged but portable design is ideal for both permanent installations and mobile use. Massive Low End With Dual 18" Woofers At the heart of the SRX918S are two high-power 18" woofers with dual voice coils, allowing each driver to handle 1,500W continuously. They move lots of air to generate deep, powerful bass that provides a solid foundation for your mix. The woofers are made of durable materials to withstand the demands of live performance and high SPLs. Even Coverage Through Precision Waveguides The SRX918S uses precision waveguides to disperse the sound from its woofers evenly over a wide area. This provides uniform coverage throughout the venue so everyone experiences the same full-range mix with solid low-end. The waveguides also focus the sound where you need it, reducing unwanted energy behind the subwoofer. Advanced DSP Processing for Optimization With on-board digital signal processing (DSP), you have control over the SRX918S's sound. A 24-band EQ lets you tune the frequency response, while delay allows you to time align the subwoofer with the rest of your system. JBL's ASC filter corrects the bass response for different array sizes and the TDC filter compensates for low-end loss over distance. You can also generate pink noise to test the system without a mixing console. Rugged, Portable Design for Live Sound The SRX918S is built to handle the demands of touring and live sound. Its 18mm plywood enclosure is reinforced to minimize flex and it has an IP-54 weather-resistant rating for outdoor use. Integrated handles and three-point suspension make transporting and suspending the subwoofer easy. Overall, the SRX918S delivers professional-grade performance and reliability in a package suited for both permanent installs and mobile applications.
